Filed: 1984-04-27
Abstract: PURPOSE:To shorten the rising time of a speed in a high speed range by controlling an inverter in response to the output energy/output frequency characteristic (E/f characteristic) of the inverter with respect to the set rotating speed. CONSTITUTION:A CPU2 outputs data for controlling the speed of a synchronous motor 6 in response to the set value of a speed setter 1. A latch 3 latches the data from the CPU2, and inputs it to a D/A converter 4.

Title: Quantitative pump
Inventor: KUWABARA FUKUJI
IPC: F04B49/06
Filed: 1986-04-17
Abstract: PURPOSE:To enable the control of batch injection quantity with high accuracy, by providing a pulse oscillation circuit and making the oscillation frequency of said circuit variable. CONSTITUTION:A pulse signal S0 with predetermined frequency is outputted from a pulse oscillation circuit 1 and an electromagnetic pump member 3 is operated once per one pulse of said signal through a power photocoupler 2. A pulse counter 4 counts the number of pulses of the signal S0 and the count number N0 thereof is sent to a comparator 5. The desired number N1 of operations are preset to a setting switch 6 to be inputted to the comparator 5. When the count number N0 becomes equal to the number N1 of operations, the comparator 5 outputs a trigger signal S1. Because an H-level signal is inputted to the terminal D of D-FF 10, when the signal S1 is inputted to a terminal C, the value of an output terminal Q comes to an H-level to be held. The operation completion signal S2 from the terminal Q is inputted to the circuit 1 through an OR circuit 12 to stop the circuit 1. By this constitution, the member 31 is operated for the number of times corresponding to the number of operation times set by the switch 6 and a definite amount of a chemical liquid is accurately injected in an objective container.

Title: Ocular
Inventor: ISHIZAKA SATORU
IPC: G02B25/00
Filed: 1991-03-28
Abstract: PURPOSE:To obtain the ocular which prevents light made incident from behind from becoming stray light while aberrations are held excellent and enables an image to excellently be seen by arranging a positive single lens on the most image side and satisfying a specific condition. CONSTITUTION:The stray light is prevented from being generated by decreasing the curvature of the object-side surface of a pupil-side positive lens. Namely, the light which is made incident at a large angle from behind deviates downward and is not incident on a pupil since the curvature of a reflecting surface is small. When the pupil side curvature of the positive lens becomes large at this time, specially an off-axis comatic aberration is easily generated, so the positive single lens is used as the lens which is arranged on the most pupil side and 50<(Y1-Y2)/(Y1+Y2)<3.10 holds, where Y1 and Y2 are the object-side and pupil-side radii of paraxial curvature of the positive lens respectively. When the lower limit of this expression is exceeded, the pupil-side surface increases in curvature and when the upper limit is exceeded, the removal of the stray light becomes insufficient, so the above-mentioned condition is satisfied and the pupil-side surface of the positive lens is made aspherical to excellently compensate the aberration.

SOLUTION: Influent org. sewage A is biologically treated by a bioreactor system 6 using a humus material and after the sludge obtained is dried by a drier 8, the sludge is fermented by a fermenter 9. After smoked chaff charcoal is added by more than 3 wt.%, preferably 10-30 wt.% of the dried sludge amount to the dried sludge from a smoked chaff charcoal feeder 12, the sludge is dried by the drier 8. Further, after a 100-200 times dil. chaff pyroligneous acid to the dried sludge to be added by the charcoal is sprayed on the dried sludge by 0.6-0.9 wt.% of the dried sludge contg. about 40-50 wt.% water, the sludge is fermented by the fermenter 9. Since the smoked chaff and the chaff pyroligneous aid are added through this way, the malodor generated in the drying and fermenting process is drastically reduced.
